Abstract (en)
[origin: EP2940525A1] Provided are an infrared interactive remote control device (400) and a projection system using same, which can distinguish an indication state and an interactive control state. A pattern disc (411) which can rotate around a rotating shaft is provided in the infrared interactive remote control device (400), and in a normal state, a visible light source (403) works independently, and indication pattern holes (4112) in the pattern disc (411) are positioned on an optical path to allow visible light (431) to pass through, so that indication light spots corresponding to the indication pattern holes (4112) are formed. When a control button (406) is pressed down, the visible light source (403) and an infrared light source (404) work together, and the control button (406) synchronously drives the pattern disc (411) to rotate, so that the control pattern holes (4112) are positioned on the optical path to allow at least the visible light (431) to pass through, and control light spots corresponding to the control pattern holes (4112) are formed to indicate that the device is currently in an interactive control state.
